Frets need to be rounded to remove the flat tops after levelling, or when you dress frets to remove wear grooves. A rounded fret top is best achieved by using a rounded file !

These are diamond fret crowning files. A diamond file with a concave profile is mounted in shaped handle made of English Oak.

These files last for many fretboards : diamond is the hardest known substance known and many little diamonds are embedded in a surface plating. As the surface wears new diamonds are exposed. They are equally long lasting on stainless frets and normal nickel silver frets. The file is permanently attached to the handle.

The diamond file itself is about 35mm long and can be 2.0mm, 2.5mm or 3.0mm wide. The files are concave to match the fret profile - when in use the file stays on the fret very well, there's no chatter.

An excellent finish results and and a full polished fret is quickly obtained by using sandpaper of about 1000 grit, 1500 grit and then micromesh of 8,000 grit or over. The best job is done by going through 800, 1000, 1200, 1500, 2000 grit and then 8,000 micromesh - its only a couple of rubs with each and if you use a spring steel strip to protect the fretboard then the paper glides across the surface of the fret and strip easily.

I have geared the design of this so that its comfortable use, economic to produce, but has the full advantages of diamond abrasion. It weighs only about 40 grammes.

As always, before using any type of abrasive tools on a guitar it is recommended suitable masking (such as fretboard protector strip) is used to protect the fretboard wood and other parts of the guitar.

Diamond Files & Finishing Effort
We have used a Oak handle whcih we use in many of our other fretting tools. Diamond Files are really the best surfaces developed by mankind for abrasion - the resulting surface is by far the smoothest hand filed surface possible - hence less finishing and polishing!
